PATENT OFFICE OHIO, AssIGNOR rro PnaFE'CTION s'rovn COMPANY, or CLnvELAND, OHIO, A CORPORATION or OHIO STARTING BURNER FOR RETORT STOVES Application iled December 3, 1926. `Serial No. 152,356.

149,353, filed November 19, 1926, and SerialA No. 152,798, filed December 6th, 1926.

The fundamental purpose of .this invention is to provide an efficient and reliable 1.5 so-ealled starting burner for preheating the retorts of stoves of the class referred. to whichI utilizes the combustible mixture resulting from the injection of air under pressure into the fuel Areservoir essentially .for the purpose of forcing the liquid fuel to the retort and burners. As a consequence of this arrangement, when it is desired to start the stove (assuming that air pressure prevails in the reservoir), it is only necessary to open a valve in the connections betweenthe air space of the reservoir and the starting burner and to apply a match or other lighting means to said burner and the carbureted air issuing therefrom will ignite to preheat the retort and condition the stove for normal operation. j Y j -A Another Object is to adapt a starting burner of this nature to stoves employing removable fuel reservoirs; and, more `speciiically, to provide a construction involving a single fluid-tight joint between Vthe reservoir and a part of the stove structure to which the reservoir is detaehably con'- nected and through which part the conduits,

40 leadingto the combustion deviceand starting burner, Open into the reservoir.

Other Objects are to provide a compact,` simpleand relatively inexpensive construction that Vis convenient of installation and 4-5 admits of ready disassembly for cleaning or replacement of4 parts should the same become necessary.

With these and other objects in view, the invention may be defined as consisting of the combination and arrangement of parts defined by the claims annexed hereto and illustrated in the accompanying drawings wherein Fig. 1 is a fragmentary sectional front elevation of a stove incorporating my improved starting burner; Fig. 2 is a plan view. ofthe same with parts broken away to reveal certain connections; Fig. 3 is a sectional detail, in plan, and Fig fl, a sectional-detail, as viewed from the front, of thefconnections between the fuel reservoir and the pipe or conduit'leading to the startj ing burner; Fig. 5 is a plan view of the starting burner and adjacent parts of the stove, and Fig. 6 is a section on the line 6 6 of Fig. 5.

The stove structure comprises a top 1, legs 2 that support the top a suitable distance above the floor,.end panels 3 and 4 that extend from the front to the rear legs at the opposite ends of the stove, and a burner pan 5 that is supported a suitable distance below and parallel with the top 1.

A manifold 6 is supported within the space between the top l and the burner pan 5 by brackets 7 that are carried by and extend inwardly from the end panels 3 and L1 and have their inner Vends suitably secured to the ends of the manifold. `Burners 1() and .11 surmount the Opposite ends of the manifold 6 and are located beneath openings 12 in the stove top. Rising from about the longitudinalcenter of, and preferably formed integral with, the manifold 6 is a mixer 15 whose Outer end is turned toward the burner 10, and the same is formed with an end wall 16 which shields the downwardly directed inlet end of the .mixer from the direct heat of the burner flame. s

Secured to the outer side of the end panel 4 in about the pla-ne of the pan 5 is a unit l8that is in the form of a substantial casting and to which is adapted to be removably attached a fuel reservoir 19. Rising from the inner end of the unit 18 is a fuel pipe or conduit 20 that includes a valve 21 and connects at its upper end with a tubular retort 22 that isprojected through an aperf ture in the panel 4 and across the burner 10 and has its inner end projected through a itl) . the seat 26.

- from the stove.

hole in the end wall 16 of the mixer 15. This retort is detailed in the aforesaid application Serial No. 152,356. A valve at the inner end of the retort is controlled by a hand wheel 23 that is applied to the outer end of the valve stem 24.

As best illustrated in Figs. 3 and i, the outer end of the unit 18 is formed with a depending boss 25 that is surrounded b y an annular seat 26, and a tube 27 projects axially from the boss 25. The reservoir 19 has a neck BO that is adapted to be engaged over the boss 25 and bear, at its upper end, against a gasket 31 that is applied to Pivotally connected at 32 to diametrically opposite parts of a band that is clamped about the neck 30, are the ends of a yoke through the central portion of which a screw 36 is threaded for engagement with a depressed abutment 37 formed on the unit 18 directly above the boss 25. This screw 36, equipped as it is with a knob 38, forms a handle for carrying the reservoir when the same is detached By means of the screw the reservoir may be drawn up with its neck forced tightly against the gasket 31 thereby to effect a fluid-tight joint between the reservoir and the unit 18.

A passageway 40 in the unit 18 connects at one end with the tube 27 and at the other with the pipe or conduit 20. Air is adapted to be introduced into the reservoir through a passageway Ll1 which opens at one end through the bottom of the boss 25 and at the other through a pump fitting 42 that involves a valve, all of which is detailed in a co-pending application of Lee S. Chadwick, Serial No. 160,8Ll6, filed January 13, 192". It may be explained in passing that the air pump that is designed for use with this outfit has a hexagonal outlet extension that is adapted to be placed within the fitting 4t2 so that by turning the pump in one direction the screw valve incorporated in the fitting may be opened and, by turning it in the opopsite direction the valve may be tightly closed.

4:5 designates another passageway that opens at one end through the bottom of the boss 25 and at its opopsite end through the inner end of the unit 18 in register with an opening i6 in the end panel l, and passage of fluid through the same is controlled by a, valve ff? that cooperates with a seat 46 which surrounds the passageway at the inner end of a threaded enlargement within which the threaded portion Li8 of the valve stein i9 operates. The outer end of the stem is equipped with an operating key or handle 50. Co veniently located on the rear side of the unit 18, opposite the pump connection previously referred to, is an air gauge that communicates through a connection 56 with the passageway The air gauge is constantly subjected to any air pressure within the reservoir through the passage way 45. The end of the passageway l5 adjacent the inner end of the unit 18 is counterbored and tapped to two different depths for the reception of the threaded inner end of a nozzle 58 and the threaded end ot' an elbow fitting 59, said fitting having an air inlet 60 so as to constitute of the fitting a mixer for supplying secondary air to the gaseous mixture that issues from the orifice 61 of the nozzle 58 when the valve 47 is opened. A tube 65 leads from the fitting 59 to an elbow fitting 66 that is threaded into a bushing 67 which, in turn, is threaded into the rear end of a cylindrical portion 68 of the starting burner head designated generally by the reference character T0. The burner head incorporates an attaching plate 71 that is adapted to be secured, by a screw 72, to the end wall 1G of the mixer 15, and said attaching plate is provided with a hole through which the inner end of the retort 22 is extended. The burner head is also provided with a hood 74 which extends over the adjacent end of the retort and serves to confine the fiame of the starting burner in effective relation to the retort. The inner end of the cylindrical portion G8 is contracted slightly about an opening 75 thereby to provide an internal shoulder against which the peripheral portion of a burner screen 76 is adapted to be clamped by a sleeve 77 that is held in place by the previously mentioned bushing 67.

Preparatory to starting the stove in operation, and with all valves closed, an air pump (not shown) is applied to the fitting 42 and rotated in a direction to open the valve incorporated in said fitting and the pump is actuated to force air through the passageway 411 into the reservoir 19. When the desired air pressure has been created within the reservoir as indicated by the gauge the pump is turned in the opposite direction to close the aforesaid valve. This feature constitutes no part of my invention and for that reason is not illustrated, though details of the saine may be had by reference to the aforesaid application Serial No. 1GO,- 8426. The air confined within the reservoir becomes carbureted in the presence of the liquid fuel and upon opening the valve 47 by the nn'inipulation of its operating handle 50 the carbureted air issues from the orifice G1 of the nozzle 58 and, mixing with air admitted through the opening 60 of the fitting 59, passes on through tube (i5 to the starting burner where it may be .ignited by the application of a match or other lighting means to the region of the opening 75. The screen 7f3, functioning in the manner of the usual burner screen, controls the mixture in such a way as to cause the same to burn with a blue flame about the inner end of ing burner consisting the retort 22, the Vhood 74 deliecting the blaze along the retort for a material distance. When the retort is heatedvto the temperature required to generate gas, liquid fuel is admitted to the retort by opening the valve 2l and with the previously mentioned valve that is situated at the inner end of the retort open the gas issues from the retort into the mixer 15, Where it commingleswith air admitted through the open end of the mixer, and passes on through the .manifold 6 to the burner 10 where it may be ignited from the flame of the starting burner, after which the starting burner may be shutoff by closing the valve 47. The burner ll that is connected with the end of the manifold 6 opposite the burner 10 is controlled by a valve which may be of any approved character and the operating handle of which is designated 80.

Having thus described my invention, What I claim is l. A starting burner for use with a combustion device having a retort, said startof a self-contained unit comprising a hollow body provided with a gas emitting opening, means for supplying gas to said body, a hood projecting from the body over and beyond the aforesaid opening, and means on the body for positioning the retort of the combustion device in operative relation to said hood and opening so that the flame of the burner is diverted about and along the retort.
